VAPOR-LAMP.

To all whom it may concern Be it known that I, CHARLES NELSON, a citizen of the United States, and residing in the borough of Brooklyn, in the county of Kings, city and State of New York, have invented a certain new and useful Vapor-Lamp, of which the following is a specification.

This invention relates to a vapor lamp of the type illustrated in my co-pending application for patent filed January 17, 1913, Serial No. 742,547.

The object of the invention is to improve the devices for priming or introducing liquid fuel into the priming pan preparatory to starting the lamp. This and further objects will more fully appear from the fol lowing specification and accompanying drawing, considered together or separately.

In the drawings, Figure 1 is a vertical section of a lamp embodying the invention. Fig. 2 is a section on the line 2-2 of Fig. 1; and Fig. 3 is a vertical section of the pump shown in Figs. 1 and 2, but on an enlarged scale.

In all the views, like parts are designated by the same reference characters.

The font 1 is circular in plan. It is preferably made of sheet metal so as to be both liquid and vapor tight. The liquid fuel is introduced through a feeding opening, which is normally closed by a suitable cap 2, which is shown as attached in place by means of screw-threads. In the center of the top of the font is a circular opening surrounded by a collar 3. This collar is preferably provided with screw-threads for attachment of the wick tube. The wick tube 4 is preferably made of sheet metal. The lower portion of the tube is formed of an enlargement 5, concentric to the tube. At the bottom, the walls of the tube are doubled back, forming a sleeve 6 of greater diameter than the enlargement 5. This sleeve 6 preferably has screw-threads at its upper part for engagement of the threads upon the collar 3. The space between the enlargement 5 and the sleeve 6 constitutes an air jacket 7 The wick tube may be removed from the font by rotating it so that the threads on the sleeve 6 become disengaged from the threads on the collar 3. The parts are best Specification of Letters Patent.

proportioned so that when in position, the lower end of the tube is above the bottom of the font a sufficient distance to allow the fluid to circulate below the same. The wick tube 4 contains a wick 8.

The vapor tube 9, valve 10, outlet tube 11 and burner ring 12 are the same as that illustrated in my co-pending application previously identified. The burner ring is supported by means of a cage 13, which surrounds and is supported by the wick tube. Below the cage is a pan 14:. The pan for the purpose of containing fuel which, upon being burned, will heat the upper part of the wick tube and thus generate vapor so that the lamp may be started.

Liquit fuel is introduced into the pan 14: by means of the pump 15. This pump comprises a barrel 16 closed at both ends. Witlr in the barrel is the piston rod 17 having an operating handle 18. The lower end of the rod carries the piston 19, with valve 20 thereon. At the bottom of the barrel is the bottom valve 21. Between the bottom of the barrel and the piston is a spring 22 for normally elevating the piston. The discharge orifice 23 is arranged at or adjacent to the top of the barrel and inside of the pan 141-. The orifice is also located on the side of the barrel toward the wick tube, so that when the fuel is discharged by the operation of the pump, it will be directed toward the wick tube. Below the vapor tube 9 and secured thereto is a trough 1 1, which will catch any liquid fuel which may escape from outlet tube 11 and direct it to the priming pan. The lower end of the trough 14; is secured to the priming pan l l by means of rivets 1 1". In operation, the handle 18 is depressed and elevated a few times, which operation raises the fluid in the barrel until it issues from the orifice 23 and fills the pan 14:.

The barrel of the pump, it will be noted, is supported at its lower end by the bottom of the sleeve and the upper end by the pan.

The outside diameter of the barrel is preferably the same as the width of the air jacket, so that the barrel makes a close fit between the enlargement 5 and the sleeve 6. This produces a rigid construction and holds the pump in position when the wick tube is being screwed into or out of the font.

It is in such location that the hand of the operator will naturally grasp the pump and unless it is rigidly held in position, it is liable to be disarranged.

, According to my invention, the pump-and tube being combined in one structure, avoids the necessity of making an additional opening in the top of the font; it avoids any pipe or ther passage connecting the pump and the priming pan, and withal produces a very compact, simple and satisfactory construction.

In accordance with the provisions of the patent statutes, I have described the principle of my invention, together with the apparatus which I now consider to represent the best embodiment thereof; but I desire to have it understood that the apparatus shown is merely illustrative and that the invention 7 Copies of this patent may be obtained for and the other end by the pan, theorifice of thepump discharging'into the pan. 7

2. A vapor lamp, whichcomprises a font, a Wick tube with an enlargement adjacent to the lower end, an outside sleeve separatedfrom the enlargement and for'mlng an a1r jacket, a pan carried by the tube, a priming pump also carried by'the tube, the orifice of the pump discharging into the pan, one end of the barrel of the pump being supported the bottom of the sleeve, the other end of the barrelbeing supported by the pan and an intermediate portion of the barrel being supported by i the enlargement and the sleeve. 7 p c 9 3. A vapor lamp, which comprises a font, a wick tube communicating with the font, a vapor tube communicating with the wick tube, a priming. pan carried by the wick tube, a pump carried by'th wick tube and discharging into the priming pan, and a trough extending between and secured to the vapor tube and priming pan.
